Non-disruptive activation
You can load and activate new firmware on a switch disruptively or non-disruptively depending on the
condition of the fabric and the commands you choose. If you attempt to perform a non-disruptive activation
without satisfying the following conditions, the activation will fail. If the non-disruptive activation fails, you
will usually be prompted to try again later. If you are not prompted to try again later, the switch will
perform a disruptive activation.
To ensure that a non-disruptive activation does not fail, you should first satisfy the following conditions:
• The current firmware version permits the installation and non-disruptive activation of 6.4 firmware. Refer
to the McDATA 4Gb SAN Switch for HP p-Class BladeSystem release notes for previous compatible
firmware versions.
• No changes are being made to switches in the fabric including powering up, powering down,
disconnecting or connecting ISLs, changing switch configurations, or installing firmware.
• No port in the fabric is in the diagnostic state.
• No Zoning Edit sessions are open in the fabric.
• No changes are being made to attached devices including powering up, powering down,
disconnecting, connecting, and Host Bus Adapter (HBA) configuration changes.
• Install firmware on one switch at a time in the fabric. If you are installing firmware on one switch, wait
120 seconds after the activation is complete before installing firmware on a second switch.
• For a fabric in which all switches are running 6.4 firmware, no more than two McDATA Web Server
sessions can be open.
• For a fabric in which one or more switches are running firmware prior to version 6.4, only one McDATA
Web Server session can be open.
Ports that are stable when the non-disruptive activation begins, then change states, will be reset. When the
non-disruptive activation is complete, McDATA Web Server sessions reconnect automatically. However,
Telnet sessions must be restarted manually.
One-step firmware installation
The Firmware Install and Image Install commands download the firmware image file from an
FTP or Trivial File Transfer Protocol (TFTP) server to the switch, unpacks the image file, and performs a
disruptive activation in one step. The one-step installation process prompts you to enter the following:
• The file transfer protocol (FTP or TFTP)
• IP address of the remote host
• An account name and password on the remote host (FTP only)
• Pathname for the firmware image file
1. Enter the following commands to download the firmware from a remote host to the switch, install the
firmware, then reset the switch to activate the firmware.
McDATA4GbSAN #> admin start
McDATA4GbSAN #> firmware install
The switch will be reset. This process will cause a
disruption to I/O traffic.
Continuing with this action will terminate all management
sessions,including any Telnet sessions. When the firmware
activation is complete, you may log in to the switch again.
Do you want to continue? [y/n]: y
Press 'q' and the ENTER key to abort this command.
2. Enter your choice for the file transfer protocol with which to download the firmware image file. FTP
requires a user account and a password; TFTP does not.
